United States Patent Olilice 3,@7785 Patented Feb. 12, i953 3,077,085 COLlNG UNIT FR BEVERAGES William Derrick Johnston, 629 Kahkwa Blvd., Erie, Pa., and Alvan L. Barach, 929 Park Ave., New York, NX. Filed May 27, 1969, Ser. No. 32,173 1 Claim. (Cl. 62293) This invention relates to a cooling unit for beverages.

It is well known that when gas expands, a very rapid cooling effect results. When CO2 compressed in the container is allowed to expand, it becomes very cold. CO2 is commonly stored in small cylinders and these cylinders are relatively inexpensive. When the container is ruptured and gas allowed to escape to atmospheric pressure, both the container and the escaping gas become very cold. Since CO2 is dissolved in various kinds of carbonated beverages, the escaping CO2 from a small cylinder can be held in a glass of beverage or the gas can be allowed to bubble up through a cold beverage `and not only cool the beverage but carbonate it as well.

It is, accordingly, an object of the present invention to provide an improved compact cooling device for cooling beverages and the like.

Another object of the invention is to provide a combination cooling and carbonating device.

A further object of the invention is to provide a portable cooling device.

Yet a further object of the invention is to provide a cooling device which is simple in construction, economical to manufacture, and simple and eiiicient to use.

With the above and other objects in view, the present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportions, and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing:

FIG. l is a view of a cooling and carbonating device according to the invention; and

FIG. 2 is another embodiment of the invention.

Now with more specilic reference to the drawing, a combination cooling and carbonating device 1li shown in FIG. l has a body made up of a first hollow section 11 and a second hollow section 12 which are connected together by a threaded male extension 14. The extension 14 engages a threaded counterbore 15 in the body section 11. The hollow body section 11 has a hollow bore 16 therein which terminates in a reduced size bore 17 having a centrally located pintle 18 which has a point thereon for rupturing the seal in the neck of a hollow cylinder 19. The cylinder 19 is a conventional type of cylinder which is commonly used to contain carbon dioxide under relatively high pressure.

The hollow body section '12 has a bore 20 therein which receives the bore of the cylinder 19. A handle 21 may be inserted n a bore 22 and fastened therein by threading, brazing, cementing, or other well known fastening means.

A lateral bore 26 communicates with an axial bore 23 which extends up through the pintle 18 and conducts gas from the interior of the cylinder 19 to the outside exit end 24 of the bore 26.

To use the device, the base of the cylinder 19 is put inside ofthe bore 2G andthe body section 11 is threadably connected to the hollow body section 12. When it is desired to use the device as a cooling medium, the section 11 is tightened down onto the section 12 until the pintle 1S ruptures the seal of the cylinder 19 and allows the gas to escape through the bore 26. Therefore, when the device is then lowered into a liquid to be cooled, the gas escaping from the bore 26 will not only cool the beverage but will carbonate it.

In the embodiment of the invention shown in FIG. 2, a member 11@ has a body section 111 and another body section 112 which are threadably connected by a male member 114 which engages inside a threaded counterbore 11S. A bore 116 receives one end of a cylinder 119 and the other end ofthe cylinder 119 is received in a bore 12th A pintle 117 is integrally supported in the lower end of the bore 116. The body section 112 has a bore 123 which communicates with a bore 124 in a handle 121. The handle 121 is attached to a bore 122 by cementing, welding, or other well known fastening means.

The body section 111 has lins 126 attached thereto by pressing or 4soldering or they could be integral therewith. The tins 126 increase the rate of heat transfer from the liquid to the device.

To utilize the device, the cylinder 119 is put into the bore 12d and the body section 111 is tightened onto the body section 112. As the pintle 117 ruptures the cylinder 119, the gas will escape through the bores 123 and 1241, rapidly cooling the body sections 111 and 112. The device can then be immersed in a liquid to be cooled and the liquid will be cooled; however, the gases will bubble out through the handle 121 and will not carbonate the liouid.

The foregoing specification `sets forth the invention in its preferred practical forms but the structure shown is capable of modiiication within a range of equivalents without departing from the invention which is to be understood is broadly novel as is commensurate with the appended claim.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

A cooling device comprising a first hollow section and a second hollow section threadably connected together to form an enclosure, a cylinder containing carbon dioxide under relatively high pressure disposed in said enclosure, an elongated handle attached to said first section on the end thereof remote from said second section, a pintle on said second section attached to the inside thereof at the opposite end from said rst section, and a bore through said pintle extending from the point thereof and continuing through said second section to the outside thereof remote from said rst section, said pintle being adapted to pierce said cylinder when said first section is threadably connected to said second section and said lirst section forces said cylinder into engagement with said pintle, said carbon dioxide being adapted to dow from said cylinder, when said cylinder is pierced, through said bore to the outside of said second section remote from said handle.
